THE ORIGINAL MOLECULAR REPLACEMENT WAS ...Details: A NUMBER OF DIFFERENT DATASETS WERE USED IN THE STRUCTURE DETERMINATION IN ADDITION TO THE DATASET USED FOR THE FINAL REFINEMENT PRESENTED HERE. THE ORIGINAL MOLECULAR REPLACEMENT WAS CARRIED OUT WITH A LOWER RESOLUTION DATASET. DUE TO LARGE VARIATIONS IN THE CELL PARAMETERS, EACH NEW DATASET WAS RE-SOLVED BY MOLECULAR REPLACEMENT USING A PREVIOUS MODEL. THE SAME R-FREE SET WAS USED IN ALL CASES. STRONG NCS RESTRAINTS WERE USED IN POSITIONAL REFINEMENT. THE COMPLEX WAS DIVIDED INTO 49 TWO-FOLD NCS GROUPS. SPECIFIC RESIDUES NOT OBEYING NCS WERE IDENTIFIED AND RELEASED FROM THE CONSTRAINT. NO NCS RESTRAINT ON B-FACTOR WAS USED. AFTER REFINEMENT TO CONVERGENCE AGAINST THE WORKING SET OF REFLECTIONS, THE R- AND R-FREE VALUES OF 0.250 AND 0.287 WERE OBTAINED. A FINAL ROUND OF POSITIONAL MINIMIZATION AND RESTRAINED B-FACTOR REFINEMENT WAS CARRIED OUT WITH IDENTICAL PARAMETERS BUT AGAINST ALL THE DATA, GIVING AN R-FACTOR OF 0.2609. THE SUBMITTED COORDINATES ARE FROM THIS FINAL NON-CV REFINEMENT.RESIDUE (GLU 12 ) AND RESIDUE (VAL 17 ) ARE LINKED TOGETHER FOR CHAIN B AND O. SEQUENCE ASSIGNMENT FOR THIS FRAGMENT IS AMBIGUOUS.
